If "group" is the name of the group then use

  {% for host in groups['group'] %}

or, simply

  {% for host in groups.group %}

If "group" is the variable with the name of the group use

  {% for host in groups[group] %}

  shell> cat table.html.j2
  {% for host in ansible_play_hosts %}
  {{ host }} {{ hostvars[host]['field1'] }} {{
hostvars[host]['field2'] }}
